A wheeled personal mobility device that incorporates a seat-support system for a person with a disability or a person without the full capacity to walk (not bariatric) designed to be manually propelled and steered by the rotation of both rear wheels by the occupant, and when needed, power from an electric motor replaces manual wheel rotation. The device cannot be folded or readily dismantled for transport. Typically, the user is a paraplegic or quadriparetic person who desires to manually propel himself as much as possible for the exercise. The power assist feature is enabled to climb inclines, for extended distance travel, or when the user fatigues.
